Drive-chain.



ation of the chain, will be between the central l pin and the side bushing 2 that is carried by the plates l of the intermediate link.

lt will be obvious that various other forms of means may he designed i'ii accordance with the spirit of iny invention, for preventing the free and complete rotary inovement oi' the central pin member of the piiitle While permitting a limited rotary or oscillating movement thereof.

Having now described my invention, what I claim as neu'v and desire to secure by Letters Patent is 1. A drive chain havin links composed of a plurality of plates provided with apertures at their ends, three part pintles extending through said apertures and comprising two side parts or bushings and a central cylindrical pin normally tree to turn upon one of the bushings, and means for restraining said central pin from 'making a' free and complete rotary movement.

2. A drive chain having links composed oi a plurality of plates provided 'with apertures :it their ends, three part pintles extending through said apertures and comprising two side parts or bushings and a central. cylindrical pin normally free to turn upon one oi the bushings, and means' for preventing a complete rotation of the central pin but allowing partial. .rotary or oscillating movement of the same.

3. A drive chain having links composed of aplurality of plates provided with apertures at their ends, three part pintles extending through said apertures and comprising two side parts or bushings and a central cylinessaies drical-pin, the apertures in the outside link plates being so formed as to prevent the complete rotation ot' the central pin.

4. A drive chain having links composed ot a plurality of plates provided withy apertures at their ends, three part intles extending through said apertures an comprising two side arts or busliings'and a central cylindrica pin, some of the plates having apertures so formed as to prevent the complete rotary movement of the central pin.

5. A drive chain havin links composed of a plurality of platesv provided with apertures at their ends, three part piiitles extending through said apertures and comprising tvvo side parts or bushings and a centralcyliiidrical pin having a shouldered end extending through an aperture in an outside plate, the said aperture being 'so formed as to prevent a complete rotary movement of the aid inf" '.lg. y 6. A drive chain having links coinp'osetl of a plurality of plates provided with apertures at theinends, three part pintles extending through said apertures and comprising two side parts or bushings and a central cylindrical pin having shouldered. ends extending through restricted' apertures-in the outside linlr plates,h and washers riveted upon the said shouldered ends outside the plates.
